H323 connections are dropped after "virtual session timeout" is configured Technical Level
  • H323 connection is dropped after the user configures "virtual session timeout" even if the session is not idle.
  • Changing "virtual session timeout" on the service does not resolve the the issue.
  • The solution in sk113749 does not resolve the issue.
  • There are no drops or errors in the logs, but after the session timeout and the start of the dropping, the log shows “UDP/” and not "H323."

The data connections flags do not have the "refresh parent conn" flag enabled.

The control connection is not being refreshed as expected. The control data connection generates another control data connection that will finally generate the data connections. As a result, when the data connections try to refresh the control connection it is missing one layer of the connection; when it expires, the connection is removed.
